Answer: This statement ("antibiotics kill bacteria so they must kill healthy human cells too and they must be avoided at all costs!") is wrong and can be proven to be so in the following explanation about the mode of actions of antibiotics.
Explanation:
Antibiotics are drugs which are used for the treatment of diseases caused by bacteria microorganisms. According to their mode of action, they can either be bactericidal or bacteriostatic.
Bacteriostatic antibiotics work by binding to enzymes needed by bacteria to build proteins essential for their own growth and reproduction. Atypical example is the antibiotics, sulfonamide. This drug acts by inhibiting a critical enzyme called dihydropteroate synthase which are specific to the metabolic pathway of the bacteria cells for the synthesis of folic acid. This causes the bacteria to stop growing. Together with the actions of the immune system, the bacteriostatic actions of the antibiotics can effectively stop am infection without affecting the host cells.

The common grackle is a species of robin-sized blackbirds that are fairly common over most of the
United States. Suppose that long tails (L) were dominant to short tails (1) in these birds. A female short-
tailed grackle mates with a male long-tailed grackle that had one parent with a long tail and one parent
with a short tail. What is the tail length probability of their offspring?
Answer:
Long tail (Ll) = 1/2 or 50%
Short tail (ll) = 1/2 or 50%
Explanation:
This question involves a single gene coding for tail length in grackle birds. The allele for long tails (L) were dominant to short tails (l) in these birds. This means that a bird that is heterozygous (Ll) for the gene will be phenotypically long tailed.
According to the question, a female short-tailed grackle (ll) mates with a male long-tailed grackle that had one parent with a long tail and one parent with a short tail. This male grackle will have a genotype: Ll because of his parental genotype. Hence, crossing ll × Ll, the following gametes will be produced by each parent:
Ll (male) = L and l
ll (female) = l and l
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Ll, Ll, ll and ll
2 Ll out of 4 are long-tailed i.e 1/2 or 50% probability
2 ll out of 4 are short-tailed i.e 1/2 or 50% probability

Name the reproductive parts of an angiosperm. Where are they located? Explain in brief the structure
of its female reproductive parts with labeled diagrams.
Answer:
Stamen is the male reproductive part and the pistil is the female reproductive organ.
Explanation:
Stamen or androecium is the male reproductive part and the pistil or carpel or gynoecium, is the female reproductive organ of an angiosperm. Both are located in the flower of a plant. In flower, male reproductive part is present in the form of pollen located at certain height and the female part is located lower side so that the pollen falls on the stigma and reaches to the ovary where female cells or ovules is present that fused with pollen produces seed.

explain how temperature affects population size
Answer: High temperature and drying were both associated with greater per capita mortality rate. Smaller population sizes at high temperatures and drying regimes may result from increased desiccation of adults and thus higher mortality. These precipitation effects on adult production are absent at 22°C
OR
Other than toxic metals, temperature rise and low resource availability are factors that are also known to stress populations. A rise in temperature generally accelerates metabolic rates and hence population growth rate

b. cooler than usual waters in the tropical Pacific
c. warm waters traveling eastward toward South America
d. cool waters causing colder than normal temperatures in the Southeast Incorrect
Answer:
D
Explanation:
I think so
1. Coriolis effect would deflect the path of the air mass to the west.
2. A horizon would provide the best assessment of the fertility of a soil.
3. Label E is located above Label D.
4. A La Niña can be described as cooler than usual waters in the tropical Pacific
The correct options for 1, 2, 3 and 4 are B, B, D and B respectively.
The Coriolis effect is the deflection of moving air (or an object) due to the Earth's rotation. The air moving in the northern hemisphere is deflected to the right of its intended path due to the Coriolis effect. As a result, in the Northern Hemisphere, air masses traveling from high to low latitudes will be deflected west.
The A horizon, commonly known as the topsoil, contains the most organic matter and nutrients, making it the most fertile layer of soil. This is the layer in which organic components such as degraded plant matter and humus interact with mineral particles to provide an optimal environment for plant growth.
The location at latitude D, which lies above the equator and parallel to the top of the Hadley cell, is where you might expect to find the driest average conditions in the Hadley cell circulation pattern mentioned in the question (north of the equator). Due to the compression, the air in the Hadley cell becomes warm and dry as it descends, resulting in arid or desert-like conditions.
La Niña is a climate phenomenon that causes cooling of sea surface temperatures in the central and eastern tropical Pacific Ocean. It represents the inversion phase of the El Niño–Southern Oscillation (ENSO) cycle.
Therefore, the correct options for 1, 2, 3 and 4 are B, B, D and B respectively.
